To all whom it may concern:

Be it known that 1, JAMES T. DAvIsoN,

a citizen of the United States, and a resident of VVestfield, in the county of Hampden'and State of Massachusetts, have invented new and Improved Belt Cutting and Trimming Machines, of which'the following is a full, clear, and exact description.

This invention relates to improvements in belt cutting and trimming machines, an object of the invention being to provide a machine of the character stated which will cut or trim a belt, strap or like device, the cut beginning at either side of the belt, or either end of the belt, or between the ends of the belt, as may be desired.

A further object is to provide a machine of the character stated, which is strong and durable, simple in construction and operation, and which greatly expedites and improves the cutting or trimming of belts and the like.

-With these and other objects in view, the invention consists in certain novel features of construction and combinations, and arrangement of parts, as will be more fully hereinafter described and pointed out in the blade 8 is secured by screws 9 to the re-.

claims.

In the accompanying drawings, Figure 1 is a view in side elevation illus: trating my improved machine.

Figure 2 is a sectional plan view on the line 22, of Figure 1.

Figure 8 is a view in end elevation.

Figure 41 is a view in transverse section on the line 44:, of Figure 1. g

1 represents a base or bed to which a frame 2 is rigidly fixed. This frame QfBX- mit the knife to cut with equal facilityin both directions of movement.

Belt supporting platforms 10 and 11 re-- spectively are secured upon blocks 12 on.

base 1 and have upwardly projecting flanges 1 922. I Serial no 564,694.

13 at their side edgs, against which a belt or-thelik'e can bepositionede Y It will be noted that these platforms 10 and 11 are located at opposite sides of the:

blade 8, or in other words, the blade 8 moves betw'een the platforms 10 and '11 to sever a belt, or to trim a belt resting on either or both'of the platforms.

The block 6 is provided with a screw threaded opening 14: receivinga screw 15, the latter having suitable bearings at its ends in the frame 2 and at one end is'provided with a inion 16', which is driven by a gear wheel 1 on a short drive shaft 18, and a crank arm 19 is secured on the shaft 18 to turn the latter. A suitable housing 20 encloses the gear 17 andpinion 16 as shown. v V

The operation is as follows:

A belt or otherdeviceto be cut, is placed on one, or both'of the platforms 10 or 11 and the knife 8 is caused to move he- .tweenjthe platforms to cut, or sever the belt. This movement of the knife, or blade, is caused by the-rotary. motion of the screw 15 engaging the screw threaded'opening 14 of block 6 and motion is imparted to the screw through the medium of the pinion 16, gears 17, shaft 18 and crank 19, as will be readily understood.

Various slight changes might be made in,

the general form and arrangement of parts described without departing from'my invention, and hence I do notlimit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall. within the spirit I claim:

and scope of the appended claims.
